Since before graduating high school, I have been involved in the technology field. My core competency is in problem-solving, staff training, and technical support, but as the sole contractor in many places, I have expanded into roles in Linux and Windows server Administration, IIS Services, C++ scripting, and Administrative support and budgeting.
My professional work experience began as a jack-of-all-trades at the local library, and soon expanded to systems and network administration roles at libraries in nearby towns. I have recently received my B.A. in Business Information Systems, adding to my A.A.S in Microcomputer Support Specialist and A+ Certification.

I am an extremely skilled, motivated, and highly knowledgeable IT professional with 15+ years in the IT industry. I am also an EC Council Certified Ethical Hacker, and in addition to security services, I provide a vast array of technical solutions to both businesses and individuals. From network/server/workstation planning and implementation to advanced troubleshooting and traffic analysis, I am THE answer to your technical demands. Add to this the fact that technology isn't just my profession; it's my passion, and you will discover why my clients have been with me for years and wouldn't consider switching. I absorb and become well-versed at any issue thrown my way, and will get to the bottom of whatever roadblock I encounter.
Who I am not: your average neighborhood tech geek, a rep from a fly-by-night shop, or someone sending proposals to any listing that appears. I choose my applications very carefully, and make sure I have budgeted enough time to complete the task required. I also do not apply for jobs that I'm not 100% certain I can handle. Due to these and many other reasons, I have built a solid name for myself locally, and will do so here as well. You'll be glad you chose to have done business with me, and I look forward to meeting your technological challenges head-on.
